by the heating device and the dinner pail may be connected together and detached when required.

'Another object of our invention is to provide means whereby the draft to support the flame of the heating device may be regulated.

These'and other objects are attained by means of the construction illustrated in the accompanying drawing, in which Figure 1 is a vertical sectional view of a dinner pail and heating device therefor made in accordance with our invention. Fig. 2 is a side elevation of the same.

Referring to the accompanying drawing for a more particular description of our invention, the numeral 1 designates a heating device for a dinner pail comprising an oil reservoir 2 and a burner 3 secured in the upper end of said reservoir, said burner being provided with wicks 4 and designed to burn kerosene oil. The upper end of the burner 3 projects into a heating chamber 5, said chamer having a draft tube 6 extending upward therefrom and terminating at its upper end in an outlet provided with a series of perforations 7. Fitted to the outlet is a cap 8,

said cap having a series of perforations 9 in f the sides thereof, said perforations adapted tol bef'brou ht into register with the perforations 7 int e tube 6. Secured to the cap 8 is a series of hooks 10, said hooks serving to engage the upper edge of the tube 6. to hold the cap in p ace said hooks also servin to permit said cap to be adjusted to regu ate the draft of the heating device, as will be understood. In the side of theheating chamber 5 is a sight opening 11 comprising a pane of glass or other transparent material. A flange 12 is secured Within the chamber 5 to provide a support for the dinner pail.

The body portion of the heating chamber extends above the flange 12, and an ear 13 is secured near the upper edge of the extended portion. A dinner pail 14 of usual, or any suitable construction, is adapted to rest upon the flange 12 within the extended portion of the heating chamber, the bottom of said dinner pail being disposed immediately above the burner 3. The heater is hinged, as at 15, to the lower end of the heating .chamber 5, and a spring latch 16 at the opposite side of the heating chamber is adaptn ed to swing over a lug 17 formed on the heater. Connected to the ear 13 is.awire keeper provided with a hook 18 designed to engage an opening 19 in the ear 13, and the upper end of said keeper having an angular y bent end 20 which engages the bail ear 21 of the dinner pail 14. A similar keeper 22 is provided for the opposite side of the device.

The operation of our invention may be briefly described as follows: The dinner pail 14 is connected by means of the keepers to the heating device and may be carried with the same. When it is desired to heat the contents of the dinner pail the burner is lighted and when sufficiently heated the keepers may be detached from the bail ears of` the dinner pail, and the lattervis removed and the burner extinguished. To regulate the draft of the burner the cap 8 is adjusted upon the tube 6 so that the perforations 7 and 9 will be out of register, thus permitting the air to low out through the openings 8a in the top of the cap.

Having thus described the invention, what is claimed as new, is

A device of the character described comprising an oil reservoir with a burner, a heating apparatus mounted over the burner and having a central supporting flange to provide an extension which serves as a rece tacle for the lower portion of a dinner pal to ermit of the bottom thereof to rest on the ange, said pail being provided with ears, a

draft tube arranged at one side of the heater In testimony whereof, We affix our signaand extending upwardly therefrom, means tures in presence of two Witnesses. seeured on the opposite sides of the heater Y having extensions pvoted thereto, provided VAUGH 5 With angularly bent upper ends'WhiCh serve A to Contact With the ears of the dinner pail to Witnesses:

hold the same and the heater together, suh- J. L. RALsToN,
